y, of which `thefollowing is adescription.

l My Vinventionrelates to that class of devices known .as "traps for water-relief valves employedupon various parts of a steam systeml to vdischarge the Water of con- Y deusation Withoutfthe unnecessary Waste of steaui.' The object of'rnyinvention is to produce a I5` rahle in construction, reliable inoperation, "and one not liable to' become cloggedand in-` operative in use through incrustation or ac` cumulations of dirt or foreign material within the valve.A y To `this end my invention consists in the `novel construction;arrangement, andcombination `of parts herein shown anddescribed, and more'particularlyy pointed out in the z5 claims.

A float 7 Oi' any .suitable OIIn or style 1s attached to 6o the tubular valve 5, so that the liquid Within the casing 1 may control the relative position ofthe valve to the valve-seat.

Where desirable, a vent 8 may be provided near the upper part of the case 1 to permit 65 air or gas entrapped in the casing*passingV into the tubular valve 5 and thence to the outlet 3. In the preferred construction an open tube .Qextends 'from near the bottom of the casing 7o 1 u 'Ward and connects to the recess 6, `or, if pre erred,.a similar tube 15 may be attached to the tubular valve 5, as shown in Fig.` 5', or

` some cases two such tubes may be pro- -vided,..one' attached to the recess 6 and the 75 other to the valve 5 as shown,vthe object being to permit a small constant discharge of lifuid from the casing 1 into the outlet 3 at al times when the device is inoperation,thus

among. other advantages 'providingfor au- 8c tornatically raining the device when the' steam-supply iscut o.

The tubular valve-seat 1i may be `formed l in any desired manner to cooperate with the 'Y tubular valve `5 and control t 1e outlet-open-l vS5 111g 3- A As hown in Fig. 1, the valve-seat is'arf ranged to project Within the tubular valve 5, the upwa y movement of which exposes the' openinvsl', permitting ,fluid topass' through 9o the outlet. ,In Figs. 3 and 5 a similar arran` ementis provided, except that the'endof t `e valve` projects 'into the valve-seat.A 4Obviously, iowever, the operation in each forni is substantially the same.4 In the-form shown g 5 inv Fig;.1 also the recess 6 is formed as an anfnulargroove formed in the cap 11 ofthe cas.-

ing 1, .while ini Figs. 3v andy` a'plainv cylindrical opening is provided. "Obviously the..
